So I was trying to figure out how one would go about creating some sort of Minecraft based animation. I am accustomed to Blender's workflow, and I was wondering if you could change the snap units (the ones used when holding Ctrl AND Shift+Ctrl) from 1 grid size and 0.1 grid size to 1 BU (not grid size) and 0.0625 (not grid size and 1/16 because there are 16 pixels in a block in Minecraft, therefore you'd have to move by 1/16 of a unit a lot). I guess an alternative would be changing the grid size to decrease by 1/16ths.
I don't mind having to write a Python script for this. I would assume this would be something that would need a script.
